The TBMDA7 modulated wideband driver amplifier is designed to provide an inexpensive signal source for immunity testing of electronic building blocks and products. It operates in the frequency range from 1 GHz to 3 GHz and is designed to be driven by the tracking generator output of spectrum analyzers. With a 1dB compression point of 350 mW avg. and a saturated output power of 500 mW avg., it can boost the output power of a tracking generator to drive Tekbox near field probes in order to find the sensitive spot of an electronic circuit or to create electric fields up to 150V/m CW, 80V/m AM when driving the Tekbox TEM Cell TBTC 0, 80V/m CW, 45V/m AM when driving the TBTC1, 40V/m CW, 25 V/M AM when driving the TBTC2 or 27V/m CW, 15V/m AM when driving the TBTC3. Test signals for immunity testing can be CW, AM or PM. The TBMDA7 provides built in modulation capability to generate 1 kHz AM or PM signals. In PM mode, the TBMDA7 can also generate a 217 Hz Signal with 12.5% duty cycle in order to simulate mobile phone TDMA noise.
